Description

Technical Field

[0002] Pipeline construction is an extremely important construction technology for laying pipelines. Pipe jacking construction technology has been widely used at home and abroad. It can cross roads, railways, rivers, and even pass under buildings without excavating the ground. It is a safe, effective and environmentally friendly construction method.

[0003] Pipe jacking construction typically involves layers of silt, where decaying plant and animal matter can generate toxic gases underground. Construction workers consume significant amounts of oxygen within the pipelines, and if oxygen deficiency or excessive toxic gas concentrations occur within the pipelines, these conditions can severely impact their health. Therefore, in addition to employing ventilation measures to improve the working environment during construction, regular hazardous gas testing is also necessary to ensure a safe construction environment. This requires a pipeline gas detection system to monitor internal gas levels within the pipelines.

[0004] Most existing detection systems first fix the detection equipment inside the pipeline, use the equipment to detect the air inside the pipeline, and transmit the detection data to the outside, so as to facilitate people to remotely detect and view the gas, and even more conveniently monitor the gas in real time. However, the air inside the pipeline is turbid and there is a lot of floating dust. When the air is detected for a long time, the dust is easy to adhere to and accumulate at the detection equipment. Too much dust can easily affect the accuracy of air detection, which is not conducive to air detection. Utility Model Content

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] An embodiment of the present application discloses a pipeline gas detection system.

[0036] Reference Figure 1 、 Figure 2 and Figure 3 A pipeline gas detection system includes a top plate 1, a detachable detection box 2 is installed at the bottom of the top plate 1, and a plurality of snap-in boxes 4 are fixedly connected to both ends of the detection box 2. The top plate 1 and the detection box 2 are fixedly connected through the snap-in boxes 4, an air detector 7 is fixedly connected to one side of the interior of the detection box 2, a detachable dustproof net 3 is installed at one end of the detection box 2, and an exhaust fan 8 is fixedly connected to the other end of the interior of the detection box 2, a dust exhaust fan 9 is fixedly connected to the bottom end of one side of the interior of the detection box 2, a brush assembly 5 is installed on one side of the interior of the detection box 2, and a controller 6 is fixedly connected to one side of the detection box 2, and the controller 6 is electrically connected to the air detector 7, the exhaust fan 8 and the dust exhaust fan 9.

[0037] When testing the air inside the pipeline, the top plate 1 and the detection box 2 can be assembled and fixed by the snap box 4 first, and then the external strong adhesive can be attached to the top plate 1, and the top plate 1 can be glued to the inside of the pipeline to fix the detection box 2 inside the pipeline. The controller 6 is equipped with a control chip, an instruction receiving chip and a data transmission chip. People can remotely control the controller 6 through the hand terminal and turn the exhaust fan 8 and the dust exhaust fan 9 on and off through the controller 6. When testing the internal air, the controller 6 can turn on the exhaust fan 8. Through the operation of the exhaust fan 8, the air inside the detection box 2 can be extracted, so that a negative pressure is formed inside the detection box 2, and the outside air can enter through the other side of the detection box 2, so that the air circulates inside the detection box 2. The circulating air can be tested by the air detector 7, and then the oxygen content and harmful gases in the air are tested. The test results can be transmitted to the external hand terminal through the controller 6 so that people can check before construction, thereby providing protection for the safety of construction workers.

[0038] When air circulates inside the detection box 2, most of the floating dust in the air can be blocked by the dustproof net 3, thereby reducing the external dust from entering the detection box 2 to ensure the detection accuracy of the air detector 7. After a long period of detection, the inner wall of the detection box 2 will be stained with dust. When the inside of the detection box 2 is cleaned, the internal structure of the cleaning component 5 can be used to clean the inner wall of the detection box 2 and the dustproof net 3 under the operation of the cleaning component 5, and then the dust is brushed off from the inner wall and the dustproof net 3. At this time, the dust exhaust fan 9 is turned on by the controller 6, so that the dust exhaust fan 9 discharges the air inside the detection box 2, and then cooperates with the operation of the cleaning component 5 to discharge the dust from the detection box 2, thereby realizing the cleaning process, thereby keeping the internal space of the detection box 2 tidy, reducing the dust inside the detection box 2 from affecting the accuracy of the air detector 7 in detecting the air in the pipeline, thereby improving the detection accuracy.

[0039] When the air detector 7 needs to be maintained and cleaned, the clamping box 4 can be manually operated to make the internal components of the clamping box 4 operate, and then the components of the clamping box 4 can be released from the clamping restrictions on the components of the top plate 1, thereby realizing the separation of the top plate 1 and the detection box 2, thereby realizing the rapid disassembly of the top plate 1 and the detection box 2, thereby facilitating people to maintain, inspect and clean the inside of the detection box 2, thereby facilitating people's use.

[0040] Reference Figure 4The brush cleaning assembly 5 includes a motor 51 fixedly connected to one side of the bottom of the detection box 2, and a threaded rod 52 is fixedly connected to the output end of the motor 51. The threaded rod 52 is rotatably connected to the detection box 2. A sliding rod 53 is fixedly connected to one side of the interior of the detection box 2. A brush is installed on the threaded rod 52, and the brush includes a U-shaped plate 54 threadedly connected to the threaded rod 52. A plurality of brushes 55 are fixedly connected to the side of the U-shaped plate 54, and the other end of the U-shaped plate 54 is connected to the sliding rod 53.

[0041] When the motor 51 is running, the threaded rod 52 can be driven to rotate, and the rotating threaded rod 52 can drive the U-shaped plate 54, so that the U-shaped plate 54 is moved up and down on the threaded rod 52, thereby driving multiple brushes 55 to move up and down. The multiple moving brushes 55 can respectively clean the inner wall of the detection box 2 and the dustproof net 3, so as to brush off the attached dust, and cooperate with the dust exhaust fan 9 to discharge the dust, thereby realizing the cleaning process.

[0042] Reference Figure 5 and Figure 6 , both sides of the bottom of the top plate 1 are fixedly connected with mutually symmetrical plug-in blocks 11, and a card slot 12 is provided at the bottom of the plug-in block 11. An inner bottom end of the inner side of the card box 4 is provided with an inner cavity 41, and an extrusion piece is installed inside the inner cavity 41, and both sides of the top of the inner cavity 41 are fixedly connected with an inclined elastic card 42, one end of the elastic card 42 is fixedly connected with a card block 43, and the outer side of the card block 43 is coated with a rubber layer. The extrusion piece includes a connecting rod 45 that passes through and is connected to the inside of the inner cavity 41, and one end of the connecting rod 45 is rotatably connected to an extrusion block 44, and the extrusion block 44 is slidably installed inside the inner cavity 41. The inner cavity 41 is penetrated by the connecting rod 45 and is provided with an external thread, and the bottom end of the connecting rod 45 is provided with an internal thread that matches the external thread.

[0043] When the top plate 1 and the detection box 2 are spliced, the insertion block 11 can be inserted into the card box 4. At this time, the two elastic cards 42 are inserted into the card slots 12. At this time, the connecting rod 45 is manually pushed so that the connecting rod 45 drives the extrusion block 44 to slide inside the inner cavity 41, and then slides out of the inner cavity 41 and enters between the two elastic cards 42. The two inclined elastic cards 42 can be pushed up by the extrusion block 44, so that the elastic card 42 is pressed against the inner wall of the card slot 12 and drives the card block 43 to be embedded in the groove inside the card slot 12. At this time, the connecting rod 45 can be rotated to thread the connecting rod 45 on the card box 4, thereby fixing the extrusion block 44 and then making the card block 43 be clamped and fixed inside the card slot 12, thereby realizing the clamping and fixing of the top plate 1 and the detection box 2. The rubber layer coated on the outside of the card block 43 can enhance the friction between the card block 43 and the inner groove of the card slot 12, thereby improving the clamping strength.

[0044] Reference Figure 2A symmetrical slider 21 is fixedly connected to the inner side of one end of the detection box 2, and a slide groove is opened on both sides of the dustproof net 3, and the slider 21 is installed inside the slide groove.

[0045] When the dustproof net 3 needs to be replaced, after the top plate 1 and the detection box 2 are separated, the dustproof net 3 can be manually pulled so that the slider 21 is pulled out from the inside of the slide groove, and the dustproof net 3 can be pulled out from the detection box 2, thereby replacing the dustproof net 3.

[0046] Working principle: When testing the air inside the pipeline, the top plate 1 and the detection box 2 can be assembled and fixed by the snap box 4 first, and then the external strong adhesive can be attached to the top plate 1, and the top plate 1 can be glued to the inside of the pipeline to fix the detection box 2 inside the pipeline. The controller 6 is equipped with a control chip, an instruction receiving chip and a data transmission chip. People can remotely control the controller 6 through the hand terminal and turn the exhaust fan 8 and the dust exhaust fan 9 on and off through the controller 6. When the internal air is tested, the controller 6 can turn on the exhaust fan 8. Through the operation of the exhaust fan 8, the air inside the detection box 2 can be extracted, so that a negative pressure is formed inside the detection box 2, and the outside air can enter through the other side of the detection box 2, so that the air circulates inside the detection box 2. The circulating air can be tested by the air detector 7, and then the oxygen content and harmful gases in the air are tested. The test results can be transmitted to the external hand terminal through the controller 6 so that people can check before construction, thereby providing protection for the safety of construction workers.

[0047] When air circulates inside the detection box 2, the dustproof net 3 can block most of the floating dust in the air, thereby reducing the entry of external dust into the detection box 2 to ensure the detection accuracy of the air detector 7. After a long period of detection, the inner wall of the detection box 2 will be stained with dust. When the inside of the detection box 2 is cleaned, the motor 51 can be operated to drive the threaded rod 52 to rotate. The rotating threaded rod 52 can drive the U-shaped plate 54, so that the U-shaped plate 54 can be lifted and lowered on the threaded rod 52, thereby driving multiple brushes. 55 moves up and down, and multiple moving brushes 55 can clean the inner wall of the detection box 2 and the dustproof net 3 respectively to brush off the attached dust. At this time, the dust exhaust fan 9 is turned on by the controller 6, so that the dust exhaust fan 9 discharges the air inside the detection box 2, and then cooperates with the operation of the cleaning component 5 to discharge the dust from the detection box 2, thereby achieving dust cleaning processing, and then keeping the internal space of the detection box 2 tidy, reducing the impact of dust inside the detection box 2 on the accuracy of the air detector 7 in detecting the duct air, thereby improving the detection accuracy.

[0048] When the air detector 7 needs to be maintained and cleaned, the clamping box 4 can be manually operated to make the internal components of the clamping box 4 operate, and then the components of the clamping box 4 can be released from the clamping restrictions on the components of the top plate 1, thereby realizing the separation of the top plate 1 and the detection box 2, thereby realizing the rapid disassembly of the top plate 1 and the detection box 2, thereby facilitating people to maintain, inspect and clean the inside of the detection box 2, thereby facilitating people's use.
